OPERATING PRINCIPLES FOR PHOTOELECTRIC …
PHOTOELECTRIC OPERATING PRINCIPLES FOR PHOTOELECTRIC SENSORS. These sensors use light sensitive elements to detect objects and are made up of an emitter (light source) and a receiver. Four types of PHOTOELECTRIC sensors are available. Direct Reflection - emitter and receiver are housed together and use the light reflected directly off the object for detection. In the use of these photocells, it is important to bear in mind the color and the type of surface of the object. With opaque surfaces, the sensing distance is affected by the color of the object. Light colors correspond to the max- imum distances and vice versa.
